Answer:
The pressure of H₂(g) = 741 torr
Explanation:
Given that:
The atmospheric pressure measured in the lab = 765 torr
The vapor pressure of water = 24 torr
By applying Dalton's Law of Partial Pressure :
Making The Pressure inside the tube due to the H₂(g) the subject of the formula :
we have:
= (765 -24) torr
= 741 torr
Answer:
<u><em>95 people can breath with five such trees supplying oxygen.</em></u>
Explanation:
Given data:
a man take in oxygen in a day : 22
(1
= 1000L)
Tree length: 33 m
Tree diameter : 0.55 m
tree produce oxygen in a year : 84,000 L
Tree oxygen in the air : 20%
1
= 1000 L
To find:
number of people can breath with 5 such trees: ?
Calculation:
Calculate the oxygen produced by 5 trees:
= 5 x 84,000
= 420.000 L
= 420![m^{3}](https://tex.z-dn.net/?f=m%5E%7B3%7D)
Calculate the air
= 420 x 100% / 20%
= 2100 m^3
Calculate the number of people:
= 2100 m^3 / 22 m^3
= 95.5
= 95 people
Answer: Option (C) is the correct answer.
Explanation:
A reaction in which two or more reactants combine to result in the formation of a single product is known as a synthesis reaction.
For example,
is a synthesis reaction.
Whereas the number of moles of either nitrogen or oxygen is not given. Therefore, we cannot tell which reactant is in excess or not.
Thus, we can conclude that the statement, this is a synthesis reaction is the true statement.
